SUCO
Suco - 0520 electronic pressure switch
The SUCO 0520 Electronic Pressure Switch is a robust, field-adjustable device designed around a ceramic thick-film sensor housed in zinc-plated steel. It offers a pressure setpoint adjustment between 0–250 bar, with factory-set differential hysteresis ranging from 2–95%. The PNP output is configured as normally‑closed by default, and a mechanical screw allows easy on-site tuning. It supports supply voltages between 18–36 V DC and uses durable Buna‑N or Viton seals. Notably, it features high overpressure resilience ensuring reliability in demanding applications.
The 0520 excels in industrial hydraulic systems, mobile machinery, and pneumatic plants where accurate monitoring, reliable switching, and ruggedness are essential. The ceramic-based sensor provides long-term stability and particulate resistance, while overpressure protection safeguards against sudden spikes. Its PNP output and voltage range make integration into PLCs or control circuits straightforward. Plus, it has a cable gland included for secure cabling. Use cases include safety interlocks, pump control, leak detection, or pressure alarm systems where precision, configurability, and durability under high pressure are priorities.
